If you preference bid for a seat, no seat lock pay.

If you proffer to displace or get displaced, you get the seat lock pay assuming you send in the decs message and seat lock yourself within 14 days of award.

Again, understood, but this is in reference to someone returning from a military LOA where you can get what your seniority will hold. Not sure if that is considered a preference for seat lock pay. I would presume it is, but not sure. Depending on the individual, they might have been displaced had they NOT been on LOA and for returning military USERA basically requires to be reinstated as if there had been no LOA.

You're seat lock vie the preference bid if you preference bid so there is no opportunity to volunteer for the seat lock to take the extra pay.

I don't see a way to know whether one would have been displaced on a prior bid of which they didn't bid since we don't know what that person's bid would have been.

If you return to any position other than the one you previously held, the company considers it as you having proffered for that position. The only exception is if your previous position no longer exists (if you were on the CRJ for instance).

So let me get this straight. If a CRJ FO went on MIL leave and then tries to return to the company 2 years later would the Captain LOA apply to him? Wasn’t it signed last year?

It applies, so they would not get displaced. Just like they did not displace other pilots who were not active. Displacement is not a benefit.

There are several LOAs that address displaced CAs. To my knowledge, the company has a different interpretation for each of them. I’m not sure if that situation has been tested to see how they treat it.
